Does anyone know of how to proove that the solution of the differential equation [tex]u_{t} = u_{xx}[/tex] is f(x+t)+ g(x-t) in general functions.

2. Relevant equations

3. The attempt at a solution

It is a pretty easy problem for normal functions, but i have no clue of how to do it in general ones!
